## TL;DR

Fixed in CLI v0.13.1: upgrade and log in again. Installed cli via homebrew as per the README.md: brew install axiomhq/tap/axiom Tried to authenticate: axiom auth login I logged in, in the browser.

## Steps

1. Issue axiomhq/cli#250 (closed, 5 comments): 👋 Hello friends. Given #230 is closed and about the go version, I decided to create a new issue rather than necro the old one. But I suspect it's the same or similar issue. Installed cli via homebrew as per the README.md: `brew install axiomhq/tap/axiom` Tried to authenticate: `axiom auth login` I logged in, in the browser.

2. [lukasmalkmus (collaborator)]: axiom auth login failing with API error 404 was a regression from the new API backend rollout. Fixed in CLI v0.13.1: upgrade and log in again.
